This is special functionality for P2P device discovery.

That depends on the driver. Some drivers handle the Probe Request frames
in firmware or kernel, others may use the AP code in
hostapd/wpa_supplicant to process the frames.

That depends on the driver. Full Probe Request frame (and other
management frames) may be delivered to hostapd/wpa_supplicant (e.g.,
through monitor interface in case of mac80211) or
EVENT_RX_PROBE_REQ/EVENT_RX_MGMT driver events may be used for this.
